NWS Tucson, AZ wrote its last area forecast discussion before the first event at Jul 7, 12:25 PM MST, 1 hour 25 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE TUCSON AZ 1225 PM MST FRI JUL 7 2006 .SYNOPSIS...AN UPPER LEVEL DISTURBANCE OVER SOUTHWEST ARIZONA SHOULD ENHANCE THUNDERSTORM ACTIVITY TODAY AS IT GRADUALLY MOVES INTO CENTRAL AND EVENTUALLY NORTHEAST ARIZONA. A REPOSITIONING OF THE HIGH SOUTHWARD WILL BRING A MORE WESTERLY COMPONENT TO OUR FLOW EARLY NEXT WEEK. THE RESULTING RELATIVELY DRIER FLOW SHOULD SLOW THUNDERSTORM DEVELOPMENT BY LATE THIS WEEKEND AND EARLY NEXT WEEK. && .UPDATE...WILL BE UPDATING ZONES/GRIDS TO ISSUE A FLASH FLOOD WATCH...RAISE POPS AND INCLUDE HEAVY RAIN WORDING. 18Z SOUNDING PRETTY MUCH TELLS US WHAT WE ARE SEEING IN TERMS OF DEVELOPMENT IN THE DRY SLOT. WE HAVE NOT WARMED ENOUGH ALOFT TO PROHIBIT FAIRLY STRONG DEVELOPMENT. THE 1.46 IN PRECIP WATER AND VERY LIGHT SE LOW LEVEL FLOW IS CERTAINLY SUPPORTIVE OF FLASH FLOODING. ANOTHER PROBLEM IS THAT THERE APPEARS A FAIRLY LARGE OUTFLOW BOUNDARY SE FROM THE YAVAPAI COUNTY STORMS...WITH THIS BOUNDARY ABOUT TO ENTER OUR CWA AND INTERSECT OUR DEVELOPING ACTIVITY. THE ONLY NEGATIVE WE SEE IS THE ANVILS ARE PEELING AWAY FROM THE STORMS WELL AHEAD OF THEIR MOTIONS AND CLOUDING OVER THE VALLEYS. THAT MAY ARREST THE DESTABILIZATION THAT IS OCCURRING...BUT NOW THAT THE DEVELOPMENT IS UNDERWAY WITH DECENT UPPER LEVEL SUPPORT...WILL GO AHEAD AND PULL THE TRIGGER IN CONCERT WITH KPSR. WILL RUN THE WATCH UNTIL 9PM...ALTHOUGH WE MAY NEED TO EXTEND IT LATER TONIGHT OVER ZONES 19/30 WHERE WARM TOP REDEVELOPMENT IS MOST LIKELY. && .PREV DISCUSSION...WITH THE UPPER LOW DEFINITELY LIFTING NNE AND EVENTUALLY SHEARING IN THE FACE OF THE UPPER LEVEL WSW FLOW...THE DOWNTURN WE WERE EXPECTING ON WED FOR LATE THIS WEEKEND AND EARLY NEXT WEEK IS STARTING TO DECENT AGAIN. HOWEVER IT IS IMPORTANT TO NOTE THAT THE RIDGING WILL NOT BE PARTICULARLY STRONG...AND 06Z GFS NEVER LOWERS OUR 700MB DEWPOINTS BELOW +5C OR OUR PRECIP WATER BELOW ABOUT 1.1. THUS WE MAY BE DOWN...BUT CERTAINLY NOT OUT. AND AFTER THE PAST 2 DAYS...OUR MODEL CONFIDENCE IS DEFINITELY NOT HIGH. && .AVIATION...TAFS AND TWEBS ADEQUATELY COVER ALL SIGNIFICANT WEATHER AT KTUS. && .TWC WATCHES/WARNINGS/ADVISORIES...FLASH FLOOD WATCH ZONES 19/30/32/33/34/35 UNTIL 9PM. && PYTLAK WEATHER.GOV/TUCSON
